Q: It is learned that Japanese right-wing activists entered the territorial sea of the Diaoyu Islands today and so did China's maritime surveillance ships for rights protection patrol. Please confirm.

A: China expresses strong dissatisfaction with and firm opposition to Japanese right-wing activists' illegal entry into waters off China's Diaoyu Islands. We are on high alert for their attempts and purposes. If nothing is done to rein in this kind of provocative activities, the situation may become even more complex. China expresses deep concern about that.
